Puffy lips are often the result of allergic reactions. These allergic reactions can lead to a condition that causes short-term swelling to occur beneath the surface of the skin, a condition known as angioedema. Puffy or swollen lips may also be caused by other conditions, such as an infection, injury, or certain hereditary conditions.
Swollen lips, or lip oedema, is when one or both lips enlarge or distend beyond their normal size. This swelling is caused by a build-up of fluid, or inflammation inside the lip tissue. It can have many causes, including injury, illness, certain medicines or allergies. Swollen lips can be a sign of anaphylaxis â a severe allergic reaction â which requires immediate medical attention. In less serious cases, swelling may appear and disappear quickly, for example after chapping or sunburn.
